To all whom, t may concern.-

Beitknown that LWILLIAM H. DooLrTrLE, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Quad-Forming Attachments for Linotype-` Machines, of which thefollowing is a specilication.

My invention has relation to quad-forming attachments forlinotype-machines, and in such connection it relates to the constructionand arrangement of the parts constituting such an attachment.

The principal object of my invention is to provide a simple andefficient mechanism adapted to be attached to the molddisk of alinotype-machine for forming quads of re quired Width; and to this endmy invention consists, iirst, in providing, in conjunction with themold-disk of a linotype-machine, a quad-mold comprising a body and acap, the body of said mold being removably secured to the mold-disk andthe cap being removably secured to the body, said cap and body havingformed between their contiguous faces a series of channels or grooves ofa Width or Widths corresponding to the Width or Widths of the quads tobe formed and With vise-jaws located adjacent to one face of the moldand With means adapted to form a backing for said mold, and, second, inproviding, in conjunction With the quad-mold, means for locking thematrix vise-jaws together during formation of the quads and the saidmeans forming a backing for the quad-mold.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection With the accompanyingdrawings, forming part hereof, in which Figure 1 is a front elevationalview of the mold-disk of a linotype-machine Witha quadlnold embodyingmain features of my invention secured thereto. Fig. 2 is a perspectiveview of the top portion of said disk, illustrating the quad-mold, thematrix vise-jaws, the clamp or fastening for said jaws, and otherauxiliary parts. Fig. 3 is a cross-sectional view of Fig. 2 and of themetal reservoir or pot. Fig. lisasectional View taken substantial] y onthe line of Fig. 1 and illustrating the ejector-plateand the quad-moldwhen said mold has moved with the mold-disk to the position indicated bydotted lines in Fig. 1. Fig. 5 is a perspective View, enlarged andpartially broken away, of the quad-forming mold detached from themachine. Fig. 6 is a perspective view, enlarged, of the clamp forlocking the matrix vise-jaws together. Fig. 7 is a perspective View,enlarged, of the ejector-plate; and Fig. 8 is a perspective view,enlarged, of one of the quads.

Referring to the drawings, a represents the mold-disk of alinotype-rnachine, which disk is provided With the usual slots a. To theface of this disk a and adjacent to a slot a is adapted to be removablysecured the body b of the quad-mold. To the bodyb is adapted to beremovably securedV the cap b' of the said mold, the contiguous faces ofthe cap and body being provided with a series: of

channels or grooves d, each groove or channel being of a Widthcorresponding to the Width of the quads d to be formed in the mold.

As illustrated in the drawings, the channels or grooves d areillustrated as being formed in the under face of the cap b, and such aconstruction is perhaps preferable, since by removing from the body h acap having a prescribed arrangement of grooves and replacing the samewith another cap having a different arrangement of grooves the quad-moldmay be quickly changed to meet the demand for quads of varying sizeswithout removing the body b from the mold-disk a. The grooved portion ofthe quad-mold is adapted to be traversed by an ej ector-plate c afterthe quads have been formed in the mold, as hereinafter described. Thisejector-plate comprises a body e, from which project the ngers or prongse of a width and number corresponding to the Width and number of thechannels or grooves in the quad-mold. The plate e is held by thespring-fingers c2 and is operated in the same manner as the ordinaryplate used s ciaor for the ejectment of the slugs usually formed in sucha machine. In front of the quadmold are arranged the vise-cap f andvise-jaws g, adapted during the usual operation of the machine toreceive and hold the matrices during the formation of the slugs. In thepresent attachment it is desirable to lock the jaws g, and thus preventtheir movement during the casting of the quads in the quad-mold. This issecured by means of the clamp-plate 7c, as illustrated in Figs. 2 and 6,having at either end a hook 7o', adapted to fit around the jaws g, asillustrated in Fig. 2, and lock the said jaws together. The plate klikewise serves as a backing for the quad-mold.

Referring now to Fig'. 3, molten metal is forced from the reservoir orpot m through the slotl a of the disk a and into the channels d of thequad-mold to form the series of quads d. The disk a when the castingoperation is continuing is in the position illustrated in Figs. 1, 2,and 3, with the quad-mold backed by the clamp-plate 7o, securing thevise-jaws g together. The mold-disk is then turned to a position wheresuitable knives or trimmers (not shown) cut olf the irregular backs ofthe quads in the mold, and then the disk is further turned until themold occupies the position indicated in dotted lines in Fig. l. In thisposition the ejector-plate c enters the mold and its fingers e eject thequads d', as illustrated in Fig. 4 of the drawings.

Having thus described the nature and object of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. Aquad-forming attachment forlinotypemachines, comprising a mold-disk,a mold consisting of a body adapted to be removably secured to saidmold-disk, and a cap adapted to be removably1 secured to the body, thecontiguous faces ot' said cap and body being provided with a series otchannels or grooves cor'- responding in width to that of the quads to`be formed, vise-jaws located adjacent to one face of said mold and meansadapted to form a backing for said mold, substantially as and for thepurposes described.

2. In a quad-forming attachment for linotype-machines, a molddisk,aquad-mold comprising a body removably secured to the disk and a capremovably secured to the body, the contiguous faces of the body and capbeing provided with channels or grooves of a width corresponding to thatof the quads to be produced, vise-jaws located adjacent to the frontface of said mold, and means for clamping said jaws together,said meansforming a backing for said mold, substantially as and for the purposesdescribed.

In testimony whereof I have hereunto set my signature in the presence oftwo'subscribing witnesses.
